Title: Method and system for determining position of vehicle
Inventor: KURISUTOSU TEII KIRUTSUOSU
IPC: G01S19/21
Filed: 1993-06-29
Abstract: PURPOSE: To estimate the position of a vehicle by receiving electromagnetic signals from a plurality of sources and forming the distance between each source and the vehicle and the position of each source. CONSTITUTION: A GPS (global position system) processing system 210 receives electromagnetic signals from a plurality of satellites 104 and the actual pseudo ranges to the satellites 104 are decided by decoding or processing the signals received from the satellites 104. The actual pseudo ranges are decided from the time differences between the time when the received signals are transmitted and another time when the signals are received. In addition, the position of one satellite 104 is projected on a 180 deg. position from the center of the earth and the effective pseudo distance of the projected satellite is decided. In addition, the position of a vehicle 200 is decided by using the calculated effective pseudo distance and the actual pseudo distances to the three other satellites 104.

Abstract: PURPOSE:To obtain a sense amplifier circuit which realizes the large capacity of a memory element and integration to a high degree by supplying a potential, oppostie in polarity to the potential of either source or drain electrode, to a common connection point. CONSTITUTION:In the sense amplifier circuit using a N-channel MOSFET on a P- type semiconductor surface, the FF type sense amplifier consists of driving transistor Trs 110 and 110' and load Trs 106 and 106' and the source or drain electrode common-connected of Trs 110 and 110' is connected to potential (Vsub) of the substrate via Tr105 supplied with signal phic at its gate. In this way, holding common connection point 111 at a negative (Vsub) potential allows a ''0'' equivalent voltage to approximate the (Vsub) value and a difference in voltage between ''1'' and ''0'' signals can be set large, so that the malfunction mergin of the memory element due to a decrease in (VDD) value can be increased. In addition, lowering the voltage of connection point 111 below the conventional earth potential expands a potential difference with contact 109 or 109' and results in the shortening of an access time until the FF is determined.
